Why does the Olympic flag have five circles?

Объяснение:

“The Olympic flag has a white background, with five interlaced rings in the centre: blue, yellow, black, green and red. This design is symbolic; it represents the five continents of the world, united by Olympism, while the six colours are those that appear on all the national flags of the world at the present time.”

The five rings represent the continents participating in the Olympic movement.

The blue ring reflects the element of water - swimming. Green - show jumping, wood energy, red - fencing, fire, yellow - running, earth energy, black - shooting, metal energy.
